Avaliação de prejuizos causados pela mosca-da-azeitona Bactrocera (Daculus) ole...
Menezes, Carla; Azevedo, Jorge; Pimentel, Reinaldo; Lopes, David Horta; Mexia, AntónioIn the Azores archipelago, the olive tree only occurs in 2 Islands, Terceira and Pico. The olive fruit fly, Bactrocera oleae (Gmelin) is the key pest for this crop on the Island of Terceira, by causing important damage. Monitoring of B. oleae adults showed the occurrence of 2 population peaks, one of greater intensity in October and another of lesser intensity, in August. For the assessment of the damage caused...
Theoretical and voltammetric studies of 5-Nitro-heterocyclic derivatives with p...
Paula,Fávero R.; Trossini,Gustavo H. G.; Ferreira,Elizabeth I.; Serrano,Silvia H. P.; Menezes,Carla M. S.; Tavares,Leoberto C.Stereoelectronic properties of nitro-heterocyclic bioisosteric congeners were investigated using theory-level quantum chemistry and cyclic voltammetry with the goal of determining physico-chemical properties that affect the redox potential of the nitro group. Molecular geometry, physicochemical properties and stereoelectronic surfaces, such as molecular electrostatic potential, and HOMO and LUMO orbitalar distr...
A autodirecção na aprendizagem do Inglês : uma história num curso profissional
Menezes, Carla Maria Xavier D'AlmadaDissertação de mestrado em Educação (área de especialização em Supervisão Pedagógica na Educação em Línguas Estrangeiras) ; O presente estudo, desenvolvido pela investigadora em 2008/2009 com uma das suas turmas de Inglês, de 1º ano, de um Curso Profissional numa escola secundária, visou explorar um sistema de aprendizagem autodirigida que propiciasse a transformação de práticas de ensino e de aprendizagem. O...
Caracterização físico-química de complexo de inclusão entre hidroximetilnitrofu...
Grillo,Renato; Melo,Nathalie F. S. de; Fraceto,Leonardo Fernandes; Brito,Charles L.; Trossini,Gustavo H. G.; Menezes,Carla M. S.Hydroxymethylnitrofurazone (NFOH) is a prodrug that is active against Trypanosoma cruzi. It however presents low solubility and high toxicity. Hydroxypropyl-beta-cyclodextrin (HP-beta-CD) can be used as a drug-delivery system for NFOH modifying its physico-chemical properties. The aim of this work is to characterize the inclusion complex between NFOH and HP-beta-CD. The rate of NFOH release decreases after comp...
Risk factors for dementia in a rural area of Northeastern Brazil
Magalhães,Manuela Oliveira de Cerqueira; Peixoto,Josecy Maria de Souza; Frank,Mônica Hupsel; Gomes,Irênio; Rodrigues,Bernardo Mota; Menezes,CarlaOBJECTIVE: To identify risk factors for dementia among the elderly in a rural area of Northeastern Brazil. METHOD: The subjects assessed were all 60 years old or older, and lived in a rural region of Bahia, a Northeastern State of Brazil. CAMDEX, a structured clinical evaluation protocol, was used for diagnosis, and applied at the home of the subjects. RESULTS: The risk factors identified were divided in accord...
Botulinum toxin type A in refractory chronic migraine: an open-label trial
Menezes,Carla; Rodrigues,Bernardo; Magalhães,Elza; Melo,AiltonBotulinum toxin type A (BT-A) has been described as an important strategy to various types of pain such as cervical dystonia, myofascial pain syndrome and headache. Although BT-A efficacy has not been proven in tension type headache, its use in migraine continues controversial. In this open trial, we evaluated the efficacy of BT-A in refractory migraine. BT-A was injected in patients diagnosed with migraine who...
Voltammetric behavior of nitrofurazone and its hydroxymethyl prodrug with poten...
La-Scalea,Mauro Aquiles; Menezes,Carla Maria de Souza; Julião,Murilo Sérgio da Silva; Chung,Man Chin; Serrano,Sílvia Helena PiresChagas' disease is a serious health problem for Latin America. The situation is worsened by the lack of efficient chemotherapy. The two available commercial drugs, benznidazole and nifurtimox, are more effective in the acute phase of the disease. Nitrofurazone is active against Trypanosoma cruzi, however its high toxicity precludes its current use in parasitosis. Hydroxymethylnitrofurazone is a prodrug of nitro...
In vitro evaluation of verapamil and other modulating agents in Brazilian chlor...
Menezes,Carla M.S.; Kirchgatter,Karin; Di Santi,Sílvia M.; Savalli,Carine; Monteiro,Fabíola G.; Paula,Gilberto A.; Ferreira,Elizabeth I.Verapamil, was assayed to record its modulating effect upon Brazilian Plasmodium falciparum isolates resistant to chloroquine. Other cardiovascular drugs known to be modulating agents in resistant malaria and/or multidrug-resistant neoplasias, including nifedipine, nitrendipine, diltiazem and propranolol, were also evaluated. Concentrations similar to those for cardiovascular therapy were used in the in vitro m...
In vitro chloroquine resistance modulation study on fresh isolates of Brazilian...
Menezes,Carla MS; Kirchgatter,Karin; Di Santi,Sílvia M; Savalli,Carine; Monteiro,Fabiola G; Paula,Gilberto A; Ferreira,Elizabeth IPhenothiazine drugs - fluphenazine, chlorpromazine, methotrimeprazine and trifluoperazine - were evaluated as modulating agents against Brazilian chloroquine-resistant fresh isolates of Plasmodium falciparum. Aiming to simulate therapeutic schedules, chloroquine was employed at the concentration used for sensitive falciparum malaria treatment and anti-psychotic therapeutic concentrations of the phenothiazine dr...
In vitro evaluation of quinidine sensitivity in brazilian Plasmodium falciparum...
MENEZES,Carla M. S.; KIRCHGATTER,Karin; DI SANTI,Sílvia Maria; A. PAULA,Gilberto; FERREIRA,Elizabeth I.Falciparum malaria represents a serious and an increasing world public health problem due to the acquired parasite's resistance to the most available drugs. In some endemic areas, quinidine, a diastereoisomer of the antimalarial quinine, has been employed for replacing the latter. In order to evaluate the use of quinidine as an alternative to the increasing loss of quinine effectiveness in Brazilian P. falcipar...
